Great for single people 4/5

By rmperash

***update 6/5/20***
The app used to silence my notifications when running but it no longer does. Was this feature removed? I can’t find it anywhere in the settings to make sure it didn’t accidentally get switched off.
I really loved this app but I noticed when I moved in with my bf that the gentle wake phase no longer worked. It couldn’t tell the difference between my bf and me. BUT I would definitely recommend it for people who sleep alone!

We need Arabic language 2/5

By i_welly4

I like this application and use it every day but it does not support the Arabic language. I hope it will be added urgently. Thank you

Wrong date 2/5

By Nytlover

Today is June 6 but the sleep cycle dated my sleep as June 4-5. How to fix that? Otherwise I like the features but the date mix up is really confusing !

Definitely sliding downhill 1/5

By DocDrea323

I’ve used Sleep Cycle for more than 10 years now. I purchased premium before it was a subscription and until recently, I’ve been a fan of it.
It started a few months ago when my Hue light stopped turning on during my wake-up period. It wasn’t a big deal because my girlfriend also used Sleep Cycle and it worked for her on her Hue light and because we get a lot of natural light in our bedroom anyway.
But over time, the integration with Hue further unraveled. At night, when I would set my alarm, my Hue light used to dim to off immediately. Then it started doing it slowly, taking several minutes. Recently, it just stopped altogether.
I tried turning the Hue setting on and off and reinstalling the Hue app to no avail. I ultimately decided to spring for the premium subscription so that I could get the online backup and uninstall my Sleep Cycle app.
However, after doing so, I could not retrieve my past years of data from the Sleep Cycle servers. I can’t log in to my back-up account. No matter what I do, I can’t. I contacted support, and they said “Have you tried logging out and logging back in?”, which is extremely unhelpful. After notifying them of that, it been radio silence.
I ultimately decided to cancel the premium subscription before I was charged. I may file a Fraud report with my state attorney general office for false advertising because the app says I still have access to all the features from my previous Premium purchase, but the Hue integration does not work. But, if you’re looking for a smart sleep tracker that works with your devices, skip this one. There has to be better ones out there.

Helps me wake up 4/5

By SuzBrindamour

Great app to help you wake when you’re already waking yourself. The alarm used to wake me up in a deep sleep and it was much harder to get up. However, on occasion it doesn’t sense when I’m awake and can’t account for the difference between my husband and I (he gets up earlier and app thinks I’m awake when calculating sleep hours). Biggest complaint is that sounds that were free now are not. I would pay something but don’t want a costly subscription.

It’s interesting. 3/5

By rae in portland

This could be a very good app but it’s got several things I don’t like. I’ve been using it about a week and I don’t think it’s changed my sleep yet. The little pieces of info that it gives you are not really new or interesting. And it will NOT LET YOU PUT IN YOUR LOCATION but it cannot determine it either!! So it thinks I’m in Iceland instead of COLORADO, and then it USES THE WEATHER FROM IT’S mistaken location. And tells you how that weather is affecting your sleep. So I have turned off most of the “premium” stuff that I paid for because it is completely inaccurate.
Then you have to leave your phone next to your bed on a table, and it should be plugged in. If I had known this I would not have bought it. That is something that I try to never do unless I am traveling. Exposure to a cell phone constantly is not good for your brain, and I think it actually makes my sleep worse!!
It records if you snore and lets you know hiw many minutes. The other night it RECORDED MY CAT SNORING!!!! This was just hilarious!!! He snores very loud sometimes, and he sounds like a person, and he sleeps up by my head!!!
😂🤣
What has been helpful is seeing how fast I fall asleep, and they have a good sound for me to fall asleep quick. It also shows how deeply you sleep. And that is good to know.
So it’s kind of good, kind of frustrating, and way too expensive for how much of it I actually use. $29 for a year and I do not imagine I will use it for more than a month.

Great app but pricing plan needs improvement 4/5

By mtnmanbud

Great app but the only subscription plan is for a whole year. That the only reason I downgraded it from 5to 4 star. At least bring back the monthly subscription plan! I don’t want to commit to a whole year for $30. I think I’ll go try another app that has a monthly plan.

Not great at detecting snoring 3/5

By Travis fun

I tried to use this primarily to get an indication of my snoring. It turns out that it doesn’t catch very much if it. I’ve used other apps that record snoring and have even run Sleep Cycle at the same time as them (on a different device). Sleep Cycle catches maybe 10% of the snoring. Listening to what the other app caught, it’s strange that Sleep Cycle missed so many obvious snoring events.
It also gave me a 100% score one night on a night when it had detected the most snoring it had ever recorded. I don’t see how that can be.

Useless 2/5

By Austinfreelancer

You need to buy the premium to get ANY useful information. Didn’t know that until after I downloaded it! You can’t listen to your snoring, you can’t get any graphs. It’s inaccurate about when I fall asleep. I know last night I didn’t fall
Asleep right away. My husband was on a late call and came to bed two hours after I went to sleep.
The graphics were nice and it looked like a great app, but you have to pay. I totally understand that, but don’t offer a free app and then turn around and tell us we have to pay to actually get useful results. Just be up front in the beginning.

Bugs and Invalid Graphs 1/5

By Molybdenum trioxide

Update: The audio recording stopped working and only shows a flat baseline now for multiple days. This app has become useless and is the same as a regular alarm clock now...
This app will stop tracking your sleep and possibly not have the alarm go off in the morning if you receive a call or text at night. Simply put, this can be disastrous. There is no point to an alarm app that isn't guaranteed to go off in the morning.
All of the data figures are also scaled incorrectly, which makes them useless. Differences between data is exaggerated and not shown in a consistent way. The developers apparently have no interest in improving these, or do not understand why accurate figures matter.

Best Sleep App! 5/5

By Bean Swagster

I've been using this app for 7 years now. I've seen it go from a simple sleep analysis to becoming a very powerful app with lots of different features. Each update brings a lot of improvement and new things. Sleep Cycle has become an absolutely essential part to my sleep routine! Definitely recommend!

Almost perfect 4/5

By anonymous.5cythe

Great app. There should be an option for a lifetime purchase and this doesn’t work with my IAP tweak installed through Cydia

Fantastic 5/5

By Northern boy56601

This app is really great. Don’t know how accurate the nighttime sound readings are, but it gives you a baseline which is important. I worried about an alcohol sleep connection, but this app helped me to realize that the most important factor for a good night’s sleep was the TIME I went to bed. I’ve adjusted accordingly.

Good 4/5

By AGNMTA

I use it every night (obviously). But I don’t like that it cost soooo much to have the premium. Other than that, I love this app. I would recommend to others who can pay for the premium. Every morning, the first thing that I do is check out how I slept that night and it really interests me how a MICROPHONE can detect how you sleep. Overall, like I said, I would totally recommend.

Sleep Cycle App 5/5

By dlars2

If you’re looking for a App to analyze your sleep, give you awesome feedback, tips on how to sleep better and not cost you a penny this is your app. This application has helped me to understand what a good sleep cycle is and what it means to get a good nights rest. Would recommend use for at least 2 months every single night (missing the occasional slumber) for the best personalized tips and feedback. This app has also helped me stop looking at my phone late at night, losing valuable sleep hours. Would highly recommend!

Excellent 5/5

By Dan Covina

Excellent way to know if you had refreshing sleep

Used to be great, now it’s trash 1/5

By kgoudey

I used to love this app - and I would use it every night. Recently, even though I do what the instructions say and put it right next to my head on my nightstand, it records my partner. Even today, it recorded him ALL NIGHT, to the point where I could see when he woke up at 6 and then was awake for the rest of the morning. We have very different sleep patterns, and I SHOULDN’T EVEN KNOW THIS BECAUSE THIS APP CLAIMS IT WON’T RECORD YOUR PARTNER. AND I never used to have a problem with it recording his snoring, but now it does. Unless they figure out how to fix it, I’m deleting the app and getting rid of premium.

Amazing app 5/5

By TimDaCow

I have been using this app for nearly 4 years now and I love it. It accurately tracks my sleep each night and with premium I can learn even more about what affects my sleep and my tendencies from night to night. Highly recommend as the premium is completely optional for anyone looking for a good sleep-tracking app

Really good 2/5

By mblling

I like it’s softer alarm sounds to wake me up. It’s nice to know if you snore while sleeping, and most of the time the sleep cycle thing looks accurate. I find that it’s really off in when you fall asleep (saying I fell asleep immediately even though I stayed up longer) or in waking up (says I was sleeping soundly until the alarm but In reality I was just awake and relaxing) I’ve never really found it to follow any scientific knowledge to wake me up, it just gets me up either at the first minute of my window or the last minute, but that could possibly be due to the fact that I don’t have a bedside table and sleep with it on the windowsill next to my bed. There’s also, I haven’t figured out why, this thing it does sometimes where the alarm doesn’t go off at all, and it just gives you a little silent “good morning!” Notification if you set it up to wake at a certain time. Obviously this doesn’t wake me up. I’ve been lucky enough to just naturally wake up about 10 or so minutes after my alarm each time, but it’s dangerous if you wait until later to wake up. I also haven’t found a way to set it to just repeat on its own every night, you have to manually tell it you’re sleeping now and set an alarm every night. So, I would say this app is good if you want a gentle alarm to wake you up for things you want to do in the morning sometimes, but not good if you need it for important things you’re waking up for.

Watch App 3/5

By Kristen997471

I’ve used sleep cycle for years, so when I saw there was a stand-alone app for my Apple Watch I got excited. I can’t get it to work though. I keep getting an error message that says “Sleep Cycle does not have permission to schedule background sessions. Would you like to enable this app to run in the background?” I click enable background, and it takes me back to the option to select a time to wake up. So I do, only to be redirected to the same error screen.
What am I missing?

Stop lecturing me! 1/5

By baenana

I started using this app for an alarm clock. The tracking is interesting. But now they’re lecturing me about my sleep hygiene. Apparently our lives aren’t stressful enough, in the developer’s opinion. Well, I’ve just removed this new source of stress: I’ve canceled my subscription and found another app.

No longer muted messages 2/5

By mnmgirl24

One thing i loved about this app was it muted all messages coming through, without blocking phone calls the way Do Not Disturb does. However, for a few months now, that’s no longer the case. I’m constantly woken up by emails and texts I receive whilst sleeping. I don’t know if it’s a big or a feature that’s been removed, but I’d definitely appreciate it returning! DND is too extreme for me, because I’m always worried of missing an important call.

Watch App could be better 3/5

By kien_h

The new standalone app for Apple Watch is a great feature, but it is unstable. It constantly freezes on the Snooze screen, and shutting down the app doesn’t resolve it. The only way to get it working again is by deleting the app off the watch and reinstall from iPhone. I have had to do this several times in the short time that I’ve been using it. Looking forward to fixes in an update soon.

Screen suddenly stays light at night 1/5

By BarelyToleratingComputers

Impossible to sleep with this app running because the screen does not go dark unless I cover the front camera. Stays lit like a beacon.

Not At All Accurate So Why Buy Premium? 2/5

By SamsNorthernGirl

Like I said above, the app is not at all accurate, so why should I pay for the premium version? I have used it for the last few weeks, placing it exactly as recommended, and not once has it been accurate as to when I fell asleep.
Take last night for example: I started the app, placed the phone face down, and after saying good night to hubby, I turned off the table lamp. Seven minutes later, hubby had to get up so I turned the light on for him. While hubby was out of the room, I picked up the phone to stop/re-start the app. When I stopped it and went to the "journal", it showed that of the seven minutes I had been in bed, I'd been asleep for six of them. Duh, no, I was wide awake all seven minutes listening to the dog snoring in her crate. I didn't bother to re-start the app.
This same issue has occurred almost every night that I've used the app. Many nights I lay awake for several minutes before deciding whether to watch Netflix or Prime on my iPad or to just get up for a while. And every morning the app says I was asleep within 5-7 minutes. I'm deleting the app.

Too much promotion 2/5

By Big_nate1234

Solid app, don't get me wrong. Customer service doesn't value its users and just cares about pushing the overpriced premium features. Just let people enjoy the app without stuffing what's basically ads down our throats. It's embarrassing the direction the app has gone since it's release when it was only a couple dollars for all the features at download.

Great app but new update seems wonky 4/5

By Dracula's Bride

Been using this app for a while and I really love it—the wake up window has made me much more functional in the morning. However, since the update, the alarm sound does not stop when I “swipe up” nor when I exit the app. It can be stopped by quitting the app but still—a little irritating.

So far so good 3/5

By Cariannabear

I’d like to give it more stars but I can’t find out if any of the stories and the other things they have to help you sleep have any biannual waves. Those waves can affect people with epilepsy. I’d like to try out some of the things, but I can’t for caution sake. I would have wrote the developer instead of this, but I couldn’t find a way to do it.

Doesn’t work 1/5

By KittehFTW

I used this and thought cool it shows how many hours I am in bed and time I am actually sleeping. Then today I forgot to stop the tracking of sleep. i noticed 3 hours later that it was still in and it still noted that I was asleep part if that time. That is proof to me that
It just gives random data and doesn’t really work.

I love the app but I hate the new sleep aid interface. 5/5

By Prootwadl

I’ve use this app for a few years, and it’s very very useful. I like the way it works, not like the way it’s put together.
Unfortunately, the new sleep interface is horrible. It takes up an incredible amount of space, and it’s hard to navigate through. Who the heck thought of this? It’s bad enough that I’m not even going to use the sleep aid feature. I’ve also noticed that it now changes the one that I have selected, so if I push the play button to get the sound I want it will pick something that I didn’t select. That’s really annoying.

Do I sleep walk? 4/5

By Lucky Folder

This app is really great, and i would totally recommend it to anyone. However, every single night, the data showed that i had taken over 100 steps! That’s insane! I never even got up to go to the bathroom. I am very sure that I do not sleep walk, so logically i have to blame the app. Somehow it must hear my blankets shifting around and think it is me walking? I would love it if the developers would let me know what in the world is happening. (PS my partner doesn’t get up to go to the bathroom either, and they are a light sleeper, so if I did get up, they would know)

Greatest sleep app! 5/5

By yessum51

Love the analysis. Love that my phone doesn’t have to be in the bed with me but on the nightstand.
Enjoying the sleep training emails that I started 3 days ago.
Used the story time sleep aid last night. Fell asleep in a nano second! Ha e no idea what the story was about. 😂 Will try it again tonight. Thanks to the app developers.

It’s great! 5/5

By RSorno

Yes it is

I had insomnia, this helps me keep track of what helps and does not. 5/5

By Vesteps

Thank you team for generating an excellent app to help our body’s get the best possible rest that our body’s desperately need right now. God Bless you and your loved ones abundantly forever!!!

Journal 4/5

By nonicknamesnopost

I wish you make a small journal entry for sudden things that happen in the day- unusual things. For example today my child graduated. Big life event! To clarify the uniqueness of the day.

great 4/5

By Kookers210

i’ve been using this app for over a year and it is almost a habit now that i use it every night. it’s easy to use, has accurate tracking, and is still useable without having to spend any money. definitely user-friendly and worth the download!

Add an Apple Watch tracker 3/5

By MJC5210

This app overall is fantastic. However, I would love the ability to be able to track sleep with my Apple Watch. I see there are options out there for that, but Sleep Cycle adding this feature will be far superior to those options. Add this, and it’ll be the best sleep tracking app to ever exist!
May I also suggest adding more Siri Shortcut abilities, such as a sleep analysis report?

Sleep on track 5/5

By Sleepeazy

An amazing resource. I had problems with sleep in the past. Although this can’t be like the machines that monitor your sleep in a hospital, it confirms that I am on track and teaches me under which circumstances I get better sleep. The alarm clock feature works amazingly well. I’ve used this app daily for years.

Alarm that you can’t turn off 1/5

By n00b888

Want to start your day in the worst mood imaginable? Download this garbage app. Days 1 & 2 were fine, but on day 3 the alarm would neither snooze or turn off. The only way to make it stop was to delete this app from my watch & phone. Not ideal. I’m taking my sleeping talents elsewhere. Very glad I hadn’t already sunk $ into the premium features. Though, maybe that’s how you unlock the ability to turn off the alarm?

Bought it years ago 3/5

By panda541

And now we have to subscribe to keep using it...sooooo nah

Please fix watch app 3/5

By Devalshah9

I used to love the watch app from over a year ago but now they have changed it to be a standalone app. I'm glad they brought it back after taking it away because the watch is the best way to guarantee waking up since it buzzes the wrist. I just wish it would integrate with the phone app like it used to and work together rather than on its own. I find it much easier to set the time on my phone than watch and would be great if it synced to watch like it used to. Please fix and 5 stars!! I love this app otherwise

completely changed my mornings 5/5

By jack perales

Even when I don’t get as much sleep as I need, this app has always been successful at waking me up such that I’m aware and ready to take on the day. Significantly decreased my tiredness throughout the day!

Bring back notification blocking, please! 1/5

By NewYorkDavid

Like virtually everybody in the world who is not some kind of robot, if I try to schedule do not disturb in advance, that will mean that sometimes it goes on before I go to bed, causing me to miss important messages, and on other days it won’t go on until after I go to bed, causing me to get woken up by alerts. I can set it manually, but if I forget, then I will not sleep through the night. And this was never a problem before I got the app, but now I have to keep my phone next to my pillow for the app to work, so even on silent my phone buzzes right in my ear.
So now my choice is either to have this app that is supposed to help me sleep waking me up most nights instead, or to have this new “feature” that’s supposed to prevent me from missing critical messages causing me to miss messages sometimes (and still wake me up sometimes).
This is not a matter of users transitioning into a new GUI. The problem is that the app no longer helps people sleep, and now it helps wake people up in the middle of the night instead. No amount of “getting used to it” is going to change that.
The solution is obvious! Make this feature optional, set by the user. People who like this “improvement” can keep it, and people who prefer a sleep app that doesn’t wake them up all night can choose to have the app block notifications by default. Please implement that feature so I can give this app the five stars it otherwise deserves.

Love this app!! 5/5

By therev589

This is absolutely one of my favorite apps on my phone! I love how it intuitively knows to wake me when I'm in my lightest sleep cycle! And the ability to track my sleep over time and watch for trends is invaluable in this crazy hectic life we lead. I totally recommend this app!

No longer works at all 1/5

By Computer 4

I’ll miss this app, but it’s instability has rendered it worse than useless, completely unusable, and seemingly harmful to my phone. This has been my go-to sleep tracking app for years. I have sleep data in this app extending back to 2013. It has been a rock until now.
Recent updates have brought new features, and broken core functionality. Instead of waking me up when I set the alarm, I have woken up to a lagging phone that I have to force reboot. No alarm. No sleep data. But hey, every time I open the app, there’s a snazzy graphic reminding me that I can use the app to make sleep aid sounds or whatever the feature d’jour is.

Inaccurate 1/5

By Fmcb e mfgmdinfnfrf

I’m up almost all night, every night. Tossing, turning, dealing with my newborn. This app ALWAYS says I slept well (80-95%???? Yeah rightttt). I only sleep 2-3 hours per night. It is NOT accurate. I’ve tried it several nights as instructed, it doesn’t seem to pick up noise and activity.

Don’t like the notifications coming through now. 2/5

By skayes

Well. I’ve been using this app for years. I paid for the full version forever ago it seems. I’ve loved it. A huge keeper point was for the notification blocking. As of a few updates ago, it no longer blocks notifications. I read another review saying the same thing so I know it’s not just my app acting up and I hate it. I read that it’s allowing for users to use their DND option in the phone. Except I never use that. I liked the ease of this app blocking things for me without remembering to set DND. I don’t work a regular set schedule at work so there’s no way I can schedule DND to come on and go off. I liked that the app blocked all the little things for me but still allowed calls. Bring back notification blocking. Or make it an option to turn on/off for users and I’d be glad to give this app the 5 starts is once deserved. I realize users who are new to the app won’t notice this being an issue for them but that’s a huge feature for me for my appreciation of the app.
Thanks “Tired Night Shift Nurse!” 😴

Great App 4/5

By NanakoOkazaki

I have been using it at least 5 years. Great App!
Just wondering why they can’t change the hour format from 12 to 24. It appends so often to accidentally change am to pm and is yotally my fault, off course, but would be nice fon’t have to think about it.

Not updating my sleep journal 2/5

By WhyWontMyNameSuffice

I’ve only had this app for 3 days. The first night, it worked great. I got a notification saying that my journal was ready the next after noon. I’ve used all 3 nights, the last 2 nights my journal hasn’t been added for Sunday night or Monday night? I’ve been using the Apple Watch app.
